The video tutorial explains a probability problem involving selecting two sweets of different types from a total of 30 sweets. The instructor first describes a traditional method that involves calculating probabilities for each pair of different sweets, which is complex. Then, a more efficient method is introduced, which involves calculating the probability of selecting two sweets of the same type and subtracting it from one. This method is shown to be quicker and more accurate. The tutorial concludes with a discussion on marks allocation for the problem.
